This next set is the start to replace the wood missing on the lock side. To start, I picked the best angle to include as much of the area as possible to sand flat. Yes, I guess you could try to precisely inlet the new wood to all the splintered busted up area on the stock, but if I did, I would no doubt still be working on that area! To me, sanding it flat results in the smallest glue line and that's what I try for.
As you can see in the first picture, once sanded flat, I score the old wood to give the glue a good adhesion surface. And I do the same on the new wood.
On the second picture I've glued in a short bit of wood. A piece of wood was broken out under the area where the tang sits, so this small piece is to repair that area.
The third picture is the Chunk to be glued on the restore the missing wood between the lock and the tang area. When doing big areas like this, it's important to match the new woods grain direction and strip orientation to the original wood!
The 4th picture shows the Chunk glued in place and trimmed down a bit.
